Factual error: Three inspectors are candidates for the 'job' of chief superintendent and one is appointed. But British police promotion doesn't work like this. Chief superintendent is a rank, not a job, and inspector is three ranks below it. Officers do not skip ranks. The only possible candidates for a post carrying the rank of chief superintendent would be an existing chief superintendent making a sideways move or a superintendent who could be promoted to the next higher rank.
